(QRANTED UNDER THE PROVISIONS OF THE ACT 01: MARCH 3, 1921, 41 STAT. 31.; i313.)

To all whom it may concern:

Be it known that 1, ROBERT FREDERICK HALL, a subject of the King of Great Britain and Ireland, and residing at Moseley, near Birmingham, in the county of Warwick, England, haveinvented certain new and useful Improvements in Machines for the Manufacture of Glass Articles (for which I have filed an application in Great Britain, No. 9922, filed July 10, 1917), of which the following is a specification.

This invention relates to rotary machines for the manufacture of glass articles, and refers more particularly to a construction, whereby I am enabled to assemble a ma chine with great rapidity and facility, as well as to remove or replace any of the unit parts as desired.

The general principle of the invention consists in constructing the machine from a number of units, each of which carries all the necessary mechanisms, or a considerable portion of such mechanisms, for forminga glass article such for instance bottle.

In carrying out my invention 1 form. the machine for manufacturing glass articles with an upper rotatable member or hitting,

connected to a lower rotatable ring or its equivalent, by a suitable number of separate and distinct units, each unit carrying a parison mould and a finishing mould, or other device for finishing the article and the mechanisms for operating or transmitting motion to the moulds or device, the construction being such that each unit can be readily removed from or placed in position in the ma chine without disturbing the mounting of the moulds and associated parts in each unit.

In some cases the unit may comprise a single elongated loop, in which is mounted a parison' mould and a finishing mould together with their associated parts. In other cases each unit may comprise two separate loops, one at a higher level, carryingthe parison mould and its associated parts, and the other at a lower. level carrying the finishing mould and its associated parts, the two loops together forming a composite elongated loop.

In order that my said invention may be more clearly understood, 1 will now proceed to describe the same as applied to a machine of the Owens type for the manufacture of hollow glass articles with reference to the accompanying drawing, in which Fig. 1 is a sectional elevation of one half of the machine, the plane of section being briefly, considered, in order to enable the general construction of the machine to be understood, but they will he found described in greater detail in my co-pending application, Serial l l un'iber 599,427 filed July 27, 1920, for machines for manufacturing glass articles The machine is supported upon wheels 1, adapted to run upon rails 2 in the neighbourhood of the furnace, in the ordinary manner.

These wheels support the main lower framework of the machine which is composed of longitudinally disposed girders 7, connected by transverse girders 8.

The. girder framework 7, 8, carries a ring 11, which in turn carries a channelled ring 12, forming the lower memberof a ball hearing. 1 1 is another ring forming the upper member of the ball bearing and to this latter is attached an internally toothed annulus 15.

Suitably supported upon the lower girder framework 7, 8 is a verticalcoliuun 16, carrying the principal non-rotatable parts of the machine.

These parts comprise-- A large cum 1? carried by brackets 18, connected in turn to vertical struts 19, carried by brackets 20 upon the column 16 Another cam, in this case a horizontal cam 21, at a higher levels A vertical cam 22 for raising and lowering the parison mould.

A horizontal cam 23 near the top of the column.

24 is another cam carried by suitable brackets on the fixed framework of the machine.

At the top of the machine, is a chamber 26 provided on the outside with a, number of projectin faces each having a circular aperture 27 %ormed therein. Bolted to each of the faces and opposite one of the apertures 27 is a hollow arm 28 which extends radially from the said chamber, Each radial arm is closed at the end, but provided with an aperture 29 for the purposes hereinafter explained.

Bolted between each one of the radial arms 28 and the annulus 15 is a column or framework, hereinafter termed the bifurcated column and it will be seen that when all the bifurcated columns are in position, they carry the chamber 26 through the intervention of the radial arms 28, and that --the Whole rotatable super-structure of the machine is carried by the bearing ring 14.

The columns are formed from castings of H section at the lower part and solid .u to the height of the trunnions 31, from w hich position to the top they are hollow, so that when each unit or bifurcated column is in position, the interior of the side frames of the column is in communication through the corresponding arm and aperture 27 with the interior of the chamber 26.

The upper part of the bifurcated column carries the parison mould and its associated mechanisms, which need not be described in detail, as they form no part of the present invention.

In the form illustrated in the drawing,

the" mechanism for carrying each parison 'erence to my present invention so'tbat it mould comprises two parallel levers 86 and 37 connected at their inner ends to the Wei hts 38, the movement of which is con trol ed by a roller 4-1 working in'the cam 22, the parison mould sections being car ricd, by a casting .48 from a link 47 to which the outer ends of. the levers 36 and 37 are pivoted.

The constructional details in connection withthe lower portion of each of the bifur' cated columns have also no immediate rotis only necessary to consider them very briefly.

110 is a. casting carried by the trnnni ns 31, and constituting a swinging tablc con trolled by a, parallel link motion from the weight 113, which is in turn rontrollcd from the donble acting cam ring- 24-.

1 The swinging! table carries the finishing or blowing! moulds and tho n'ionlinnisins for operating and closing the same.

It is not thought necessary, in the present specification to consider the general operation of the machine, which is fully explained in the previously mentioned copending application, but the advantages of the unit system of construction will be briefly considered.

As has already been explained each bifurcated column carries a arison mould and its associated parts and also a finishing mould and its associated parts, so that all the important mechanisms in connection with the manufacture of a. glass article are carried by the column. Consequently by dctaching any one of the arms 28 from the corresponding face of the chamber 26 and unbolting the lower end of the corresponding bifurcated column from the annulus 15, the whole unit, may be quickly removed, taking with it the moulds and associated parts and the rods mounted on the arm 28.

In this way should one of the units break down for any reason, it can be quickly removed and replaced by another unit, or if no unit is available, it is only necessary to close the corresponding aperture 27, and the machine will continue to work without the unit.

This unit system greatly cheapcns and facilitates the manufacture, as it enables the unit to be constructed away from the machine and placed in position when complete.

til)

It also makes repairs economical and simple and makes it rarely necessary to stop the whole machine for any considerable time.

It will be understood that the methods of construction may be varied considerably.

For instance, in place of formin the units in the shape of columns, whic are hollow for the purpose of conducting air, I may form the units of solid loops or frames, carrying the parison mould and associated parts at an upper level, and the finishing mould or its equivalent and associated parts at a lower level.

In other cases the loop may comprise two parts, one at an upper level carrying for instance the parison mould and its associated mechanisms and another at a. lower level carrying the finishing mould or its equivalent and its associated mechanisms.

This application is a division of my application Serial No. 222,257, filed Mar. 13, 1918.
